Abstract: 

We detail herein readily accessible processes to control previously unobserved robust self-assemblies of nanodiamonds (diamondoids)
in micro- and nanocrystals from their mild vapor deposition. The
chemical functionalization of uniform and discernible nanodiamonds was
found to be a key parameter, and depending on the type of functional
group (hydroxy, fluorine, etc.) and its position on the
diamondoid, the structure of the discrete deposits can vary
dramatically. Thus, well-defined anisotropic structures such as rod,
needle, triangle or truncated octahedron shapes can be obtained, and
self-assembled edifices of sizes ranging from 20 nm to several hundred
micrometers formed with conservation of a similar structure for a given
diamondoid. Key thermodynamic data including sublimation enthalpy of
diamondoid derivatives are reported, and the SEM of the self-assemblies
coupled with EDX analyses and XRD attest the nature and purity of
nanodiamond crystal deposits. This attractive method is simple and
outperforms in terms of deposit quality dip-coating methods we used.
This vapor phase deposition approach is expected to allow for an easy
formation of diamondoid nanoobjects on different types of substrates.
